Do not run-away! Oracle Performance for the Uncertain


It’s eternal. Autonomous Database yes, Self-driving maybe – at the end, one of us has to put boots on the ground if there are shortcomings in real throughput or latency. In the cloud, analysis is a bit harder, on-premises has a few features less. The Oracle RDBMS is changing, but architecture, the way how it works and its limitations are still very similar on all platforms. One dilemma will stay with us: Using precious and finite resources efficiently, while valuable time passes mercilessly.

With this background, I’d like to show you in theory and practice, how Oracle uses resources. How you can analyze with Oracle’s on-board tools what currently is going on, and how you derive from that how to proceed. There is much to influence the runtime behaviour: We’ll talk about Queueing Theory, Wait Events, AWR/Statspack, ASH, Indexes, Statistics, the optimizer, software developers, users and the janitor.

Even runaways are a topic of this entertaining session: They will bite you one day, and you have to be aware!

This talk was made for experienced Administrators and DevOperators, who want to learn more about about performance analysis and its background.

Sharing Experience from 24 Months of Database Upgrade and Migration


Sharing Experience from 24 Months of Database Upgrade and Migration Running out of support, security concerns, new features, coming operating system or hardware changes…. there is a long and versatile list of potential reasons for our customers, to change the version of their running Oracle Databases. The “choice” of situations, challenges and options for changing the version, is at least as long and as versatile as the reasons are. Oracle ACE Director Martin Klier will deliver an unveiled overview about his adventures with logical dependencies, human sensitivities, technical skulduggeries and license traps. All this happens, when one or multiple databases are to be migrated or upgraded to a new version in a controlled fashion. For A as in AIX, L like Linux, S like Solaris, V like Virtualization, W twice in Windows … there was trouble, there was a solution, and there was a new experience!
